You can put this solution on YOUR website!
x=2y-12
\n" ); document.write( "4x-4y=-16
\n" ); document.write( "First one is already solved for x, so where you see x in second equation plug in 2y-12 instead.
\n" ); document.write( "4(2y-12)-4y=-16
\n" ); document.write( "8y-48-4y=-16
\n" ); document.write( "4y-48=-16
\n" ); document.write( "4y=32
\n" ); document.write( "y=8
\n" ); document.write( "now go back up to first equation and wherever you see y plug in 8 instead.
\n" ); document.write( "x=2*8-12
\n" ); document.write( "x=16-12
\n" ); document.write( "x=4
\n" ); document.write( "So the solution is (4,8)
\n" ); document.write( ":) \n" ); document.write( "
